Description

Field of invention

The invention relates to an integrated furnace in which oil smoke is discharged downwards, according to the preamble of claim 1.

Background of the invention

The effect of an extractor hood is important for the distance between an air intake connection and a smoke-producing source. Conventional range hoods are of an upward-facing type and are installed over cooking utensils. The distance between the air intake port and the smoke producing source is usually 50 to 100 cm, which easily causes smoke diffusion and an impact on human health and environmental hygiene. The integrated system of a downward-facing smoke evacuation system with a stove is a combination of a stove and cooking utensils and is characterized in that an air intake port thereof is installed near the smoke-producing source of the cooking utensils, thereby shortening the distance of free diffusion of the smoke and the The rate of absorption of smoke is increased. However, such an extractor is still in the basic research phase and has not yet been perfected in a specifically implemented structure. In particular, a specifically combined structure of a stove, cooking utensils and a cabinet is never a simple, practical and reliable solution because the arrangement of the air exhaust is complicated, the required volume is large, it is easy for the smoke to escape and both the reliability also the maintenance are bad.

Chinese patent number CN 2 550 672 Y discloses an integrated downward smoke vent device for a range. However, the document does not solve the communication problem between the gas accumulating recesses of a plurality of furnace connections. In the circumstance that a plurality of furnace connections are installed, transmission lines are required which are arranged so that a plurality of gas accumulation tanks communicate with the blower, thereby complicating the structure of the air vent and increasing the possibility of smoke leakage, which is easy to block Causes smoke and thus reduces the overall reliability. In addition, the fan is far from the air intake ports and there are many curves, so the air losses are large and the exhaust effect is influenced. Finally, the complicated structure of the air vent continues to make cleaning difficult and increases the difficulty in removing smoke pollution.

The publications CN 2 898 669 Y and CN 2 847 105 Y each show an oven with an integrated smoke outlet, the smoke being diverted downwards.

Summary of the invention

The object of the present invention is to eliminate the disadvantages of the existing integrated furnace in which oil smoke is discharged downward, such as the complicated structure of the air exhaust, poor reliability, difficult cleaning and poor suction effect, and an integrated device one after the other downward smoke evacuator for a stove with high reliability, easy manufacture and maintenance, and good suction effect.

This object is achieved by a furnace with the features of claim 1.

A furnace according to the invention, in which oil smoke is discharged downwards, comprises a cabinet body with side walls, an upper panel and a lower plate, a plurality of recessed receptacles with a cylindrical wall being installed on the panel; a cooker installed on the sub-plate; air suction ports formed in the cylindrical wall and installed on the upper part of the wall of the receptacles; and an opening for a handle formed on one side in the wall of the receptacle. The sub-panel is installed substantially parallel to the panel, the sub-panel having a structure in the shape of a pan bottom, and the part of the sub-panel that is near the side wall of the cabinet body extends towards the panel, around a combined part of the panel and the To form sub-plate, wherein the panel is arranged on the top of the side walls, wherein the receptacles are embedded in the double-layer structure formed by the panel and the sub-panel, the wall of the receptacles with both the panel and the sub-panel connected in a sealed manner, the bezel, the sub-panel and the wall of the receptacles being enclosed to form an interconnected sealed gas accumulation chamber with the air port of a blower installed at an opening of the sub-panel; and an exhaust pipe is connected to the fan, a barrier strip covering the combined part of the panel and the lower plate is arranged on the rear side of the panel, and the upper part of the wall of the receptacles is provided with fan connections which are opposite to the air intake connections sloping downward and connected to positive pressure air flow sources via air ducts.

The barrier strip, which covers the combined part of the panel with the side wall, is arranged on the rear of the panel.

In addition, the cylindrical wall of the receptacles is locked with an annular flange of the sub-plate and the cylindrical wall is folded on the outside of the flange.

Further, the periphery of the sub-panel is provided with a folded edge, and the folded edge is attached to the top of the side wall.

Furthermore, the air inlet of the fan is installed in the middle of two receptacles.

In addition, the upper part of the wall of the receptacles with fan connections is provided with a positive pressure, wherein the fan connections are opposite to the air intake connections, the fan connections are inclined obliquely downwards and the fan connections are connected via air ducts to air flow sources with positive pressure.

During use, a large gas accumulation chamber with a negative pressure is formed between the diaphragm and the sub-plate. The air intake ports of each receptacle are all contained in the gas accumulation chamber without a special gas accumulation chamber and are connected to the air flow line. The structure of the air exhaust is simplified and the connection problem of sucking air from a plurality of furnace ports is also solved without installing additional connection pipes. The air inlet of the blower is opened directly on the lower plate and the distance to the air intake openings is very short, which makes it easier to intensify the intake of the air intake ports. The gas accumulation tank and the air vent have regular and simple structures and cannot be easily blocked by an oil stain. Thus, high reliability, ease of manufacture and maintenance, and elimination of smoke pollution are properly achieved.

The bottom plate in the form of a pan bottom according to the invention also has the effect of preventing oil leakage. Oil has a very high permeability and can penetrate conventional welded joints, causing oil leakage. The sub-plate can be formed in the shape of a pan bottom by integrated stretching / pulling, thereby avoiding welded joints and enhancing the performance in terms of preventing oil leakage.

Searing smoke is cooled quickly after entering the gas accumulation chamber, and a large amount of oil droplets condense on the wall of the gas accumulation chamber. The existing gas accumulation chamber is formed by welding flat stainless steel plates. Practice has shown that oil has a very high permeability and can penetrate micro-gaps in welded joints, causing oil to leak. The sub-plate according to the invention uses a structure in the form of a pan bottom and can be made by stretching / pulling a single plate, thereby avoiding welded joints and improving the efficiency for preventing oil leakage.

At the same time, the combined part of the panel attached to the top of the side wall and the sub-panel is easily penetrated by the condensed oil of the gas accumulation tank. After condensing, the oil droplets can flow around the rear of the screen and then the oil droplets can flow downwards along the side wall. The main strategy of existing gas accumulation tanks is to improve welding precision. The cost of the improvement is high, but the effect is not obvious. Practice has also shown that it is difficult to avoid weld defects. According to the invention, the rear side of the screen is connected to the barrier strip which covers the combined part of the screen and the side wall, so that the oil droplets are guided downwards through the barrier strip before they flow into the combined part. Then, the oil drops fall on the lower plate of the gas accumulation tank, thereby making it possible to effectively prevent oil leakage from the combined part of the diaphragm and the lower plate and solve the difficult problem of oil leakage from the gas accumulation tank at a low cost.

The structure with double-layer panels also provides effective support for the recordings. Therefore, the structure of the air vent according to the invention is very well applicable to an integrated device for cooking utensils, a stove and a cabinet.

The invention has the advantages of regular and simple construction of the gas accumulation tank and air exhaust, good smoke exhaust performance, not easy blocking by smoke, high reliability, practical care and cleaning, easy manufacture and maintenance, and no oil leakage has a compact overall structure and good applicability.
